CVE-2026-92248 GIMP CVE debrief

A flaw in the file-psd plugin of GIMP allows for a heap-based buffer overflow when generating a thumbnail preview for a specially crafted PSD image file. This occurs due to an integer overflow during the multiplication of values from an embedded JPEG header, leading to an undersized heap allocation. The buffer overflow can corrupt adjacent heap objects, potentially causing an application crash or arbitrary code execution.

Who should care

Defenders responsible for systems or applications that use the GIMP file-psd plugin, especially those processing untrusted image files, should assess exposure and prioritize patching.

Why it matters

CVE-2026-92248 is a heap-based buffer overflow vulnerability in the GIMP file-psd plugin. Defenders should care because it can lead to application crashes or arbitrary code execution when processing specially crafted PSD image files. Roles responsible for system and application security, particularly those handling image processing or GIMP deployments, should assess exposure. The vulnerability's impact is supported by the CVE record and NVD entry. Evidence is available from official sources, but verification of patch application and exposure is necessary.

  • Potential application crashes or instability
  • Possible arbitrary code execution
  • Need for verification of patch application
  • Importance of restricting untrusted image file processing

Technical summary

The GIMP file-psd plugin is vulnerable to a heap-based buffer overflow when processing specially crafted PSD image files. An integer overflow occurs during the multiplication of values from an embedded JPEG header, leading to an undersized heap allocation. This allows for a controlled memory write that can result in an application crash or arbitrary code execution. Defenders should prioritize verifying and applying patches for the GIMP file-psd plugin, especially in environments where untrusted image files may be processed, and restrict processing of untrusted PSD image files.

Defensive priority

Defenders should prioritize verifying and applying patches for the GIMP file-psd plugin, especially in environments where untrusted image files may be processed.

Recommended defensive actions

  • Verify and apply the latest patches for the GIMP file-psd plugin
  • Restrict processing of untrusted PSD image files
  • Monitor for and respond to potential exploitation attempts
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including its CVSS score and vector. Red Hat has also provided references to their errata and security pages related to this CVE. Defenders should verify patch application, assess exposure, and restrict processing of untrusted PSD image files. Evidence is available from official sources, but verification of patch application and exposure is necessary. The file-psd plugin in GIMP is affected, and defenders should focus on verifying and applying patches, especially in G
